Is there a way to program a password maker on an app?
« on: December 23, 2021, 02:35:13 am »
So I want increase my password strengths. Right now I use a simple algorithm based on the web site name Im visiting.
For example I take the password requirements: upper and lower case a number, eight characters long , one special character
CCCCCVVV =_C_onstant _V_ariable
For the letters it would be a phrase that applies to all passwords "I like coffee for breakfast: Ilcfb then to make each password unique to each site you take the first letter of the domain like gmail and convert the g to a number; the number 7 then add 110 so you always get three digits.117 So the password to gmail would be Ilcfb117

But say I want to make it more complex is their a simple way to program an app or a calculator to do this simple math? Be cool just to type in a word to something and have a password come out.
Max characters: 300; characters remaining: 191

Why not make a locally-hosted web page out of it: a local file that you open in your browser, and does the math/magik right there?

(For a graphical example, see e.g. my finite impulse filter response analysis example.  When loaded, the page does not connect to the internet in any way, and works just fine when saved as a local file and simply opened in your browser.)

Personally, I'd consider three inputs – server/domain name, common passphrase, mixing method – and one output, the password generated, when you click on a button.

The mixing methods needs to be cryptographically secure (not secret, secure); and the "randomness" is provided by the passphrase (common across the sites you use this with, or some other phrase you associate with that particular site) that you do need to keep secret.

For the page, use HTML and CSS for the layout, and Javascript (included in the HTML page itself, like in my example above) for the functionality.

Thats a good idea and I could actually host the file somewhere. If I just hosted it as IE: mydomainname.com/file.htm would anyone be able to see it if I dont put anything on it that a search engine would pick up?

It would be accessible to anyone, and secrecy is not security.

Just host it locally.

Alternatively, use a keychain application that works with your browser, and completely random passwords.  Or even your own browser password manager, with offline backup storage, and encrypt your browser preferences.  Depends on the OS, of course.
